Write the total and net ionic equations for the reaction of BaSO4 dissociation, and calculate the trial Ksp for the product formed, when 40 mL of 0.1 M Ba(CH3COO)2 reacts with 60 mL 0.6 M MgSO4 and decide whether a ppt will form
At a particular temperature, N2O5 decomposes according to a first-order rate law with a half-life of 13.0s. If the initial concentration of N2O5 is 1.0 M what will be the concentration after 10s.
A bicycle tire is filled with air to a pressure of 75. psi at a temperature of 19 degrees celcius. Riding the bike on asphalt on a hot day increases the temperature of the tire to 58 degrees celcius. The volume of the tire increases by 4.0%. What ..
